11.5 Fatty Acids and Triacylglycerols

Question 1

What are Fatty Acids?

Answer 1

Carboxylic acids, typically with a single long chain,
although they can be branched

Question 2

How are fatty acids synthesized?

Answer 2

In the cytoplasm from acetyl CoA transported out of the mitochondria.

Question 3

How many steps are involved in fatty acid synthesis and what are they?

Answer 3

5,
activation,
bond formation,
reduction,
dehydration, and
a second reduction.

Question 4

What is Palmitic Acid?

Answer 4

Only fatty acid that humans can synthesize.

Requires synthesis steps done 8 times.

Question 5

Where does fatty acid oxidation occur?

Answer 5

In the mitochondria following transport by the carnitine shuttle.

Question 6

What is β-Oxidation?

Answer 6

Opposite of fatty acid synthesis

Oxidation, hydration, oxidation, and cleavage.

Question 7

What happens to unsaturated fatty acids during cleavage?

Answer 7

Unsaturated fatty acids use an isomerase and an additional
reductase
